CRIMP FOR COLLAR-PADS.

Specification of Letters Patent No. 3,661, dated July 13, 1844.

70 all wiz-0m may concern Be it known that I, JOSEPH S. BARKDULL, ofBallston Spa, county of Saratoga., and State of New York, have inventeda new and useful Improvement in Crimping Collar-Pads, which I denominateBarkdulls Collar-Grimm and I do hereby declare that the following is afull, clear, and eXact description thereof, reference being had to thedrawings attached hereto, which make a part of this specification, inwhich* Figure l is a view of the crimp open; Fig. 2 the same closed. n y

The nature of my invention consists in constructing a crimp that may beopened to receive the leat-her and then closed bringing the leather intothe shape required in crimping. 1

The crimp is constructed in the following way; two flat pieces of woodare laid together and formed into the required shape for a collar pad asshown at Fig. 2,these are connected together on thin convex edge by ivehinges, two of which are situated at the points (a) on the upper part,where it is nearly straight; another hinge is placed just at the pointof greatest curve (Z2) and the others near the lower end (0); it will beobvious that these would not allow the two halves to open without someother apparatus in addition; the two halves are therefore cut throughacross, on lines (CZ and a) on each side of the shortest curve (o), anddetach the center from the two ends, these are connected by hinges so asto allow the ends to fall back and bring' the hinges' (a, and 0,) nearlyon `a line with each other, and thus permit the halves to open as shownin Fig. l. From the center pieces (b) segmental arms (7L) project; theyare let into these center pieces near the inner or concave edge andfastened; and

they run into the end pieces (a and c), one into each, and steady themand keep all parts in the same plane while o-pen, and guide them whenclosing up together-still nearer the inner edge of the center pieces arefour spring bolts (i), two in each piece, these project beyond the pieceon each side and catch, by means of a hooked formed end,\into the endpieces (a and c) when they are closed up against the center; athumb-piece (le) is projected from the inner edge of each center pieceand rest on the spring bolts (i) by bearing down on these, the endpieces are released-a more perfect drawing of this apparatus is shown atFig. 3, where the same letters are used to designate similar parts.

The inner edge of all the pieces or that edge which is concave, may beshielded by a plate of metal, running their whole length, and along theouter corners of these edges, there is a row of sharp pointed pins orhooks (a) that stand ont a little flaring onto these, the leather to becrimped is hitched, and it is also hitched to others at each end. Thisis done, while the crimp is open as shown in Fig. l, after which, thecrimp is closed up and the spring bolts secure the end pieces to thecenter ones; the two halves are held together by hooks (o) that areattached to one half and catch over pins (72) projecting from the other.

What I claim as my invention and desir to secure by Letters Patent is-The combination and arrangement of the parts (a, 0,) constructed andarranged substantially in the manner herein set forth.
